Single vs. double dartos layers for preventing fistula in a tubularised incised-plate repair of distal hypospadias

Figures & data

Table 1 Postoperative complications in two groups.

Complications, n (%)	Group I (double)	Group II (single)	Total	P
n patients	48	52	100
Fistulas	0	4(8)	4(4)	0.12
Repair breakdown	1(2)	0	1(1)	0.48
Meatal stenosis	1(2)^a	1(2)^b	2(2)	>0.99
Total	2(4)	4(8)	6(6)	0.44

a Meatal stenosis in Group I developed late after full healing of urethroplasty, with no associated fistula.

b Meatal stenosis was associated with a fistula in one patient from Group II.
